NixOS

Install instructions for NixOS. First open a shell with vim and git:

nix-shell -p git vim

EXT4

parted /dev/nvme0n1 -- mklabel gpt
parted /dev/nvme0n1 -- mkpart ESP fat32 1MB 512MB
parted /dev/nvme0n1 -- mkpart root ext4 512MB 100%
parted /dev/nvme0n1 -- set 1 esp on

mkfs.fat -F 32 -n BOOT /dev/nvme0n1p1
mkfs.ext4 -L NixOS /dev/nvme0n1p2

mount /dev/disk/by-label/NixOS /mnt
mkdir -p /mnt/boot
mount -o umask=077 /dev/disk/by-label/BOOT /mnt/boot
nixos-generate-config --root /mnt

ZFS

First stop the zfs-zed service, and unload the ZFS kernel modules:

systemctl stop zfs-zed
lsmod | grep zfs | cut -d' ' -f1 | xargs rmmod -f

Then add the following to /etc/nixos/configuration.nix:

boot.supportedFilesystems = [ "zfs" ];

And rebuild the system:

nixos-rebuild switch --upgrade

Partition the disk:

parted --script /dev/nvme0n1 -- mklabel gpt mkpart esp fat32 1MiB 512MiB mkpart primary 512MiB 100% set 1 boot on

Create an encrypted pool:

zpool create -f -o ashift=12 -O encryption=on -O keyformat=passphrase -O mountpoint=none rpool /dev/nvme0n1p2

Create a root partition:

zfs create -o mountpoint=legacy rpool/root
mkdir -p /mnt
mount -t zfs rpool/root /mnt

And home partition:

zfs create -o mountpoint=legacy -o compression=on rpool/home
mkdir -p /mnt/home
mount -t zfs rpool/home /mnt/home

Format the boot partition:

mkfs.fat -F 32 -n BOOT /dev/nvme0n1p1
mkdir -p /mnt/boot
mount -t vfat /dev/nvme0n1p1 /mnt/boot

Generate the configuration:

nixos-generate-config --root /mnt

Add the following to /mnt/etc/nixos/configuration.nix:

boot.initrd.supportedFilesystems = [ "zfs" ];
boot.supportedFilesystems = [ "zfs" ];
services.zfs.autoScrub.enable = true;

networking.hostName = "Aloria";
networking.hostId = "abcdef01";

Install

Then either clone the repository:

git clone https://git.thomasave.be/thomasave/Dotfiles
sudo nixos-install --impure --flake ./Dotfiles#Aloria
mv ./Dotfiles /mnt/home/user/.dotfiles
sudo ln -s /home/user/.dotfiles /mnt/etc/nixos

Or install it directly:

sudo nixos-install --impure --flake git+https://git.thomasave.be/thomasave/Dotfiles#Aloria

Post-install

Clean-up:

umount /mnt/{home,boot}
umount /mnt

If using ZFS:

zpool export -a
